From Rock Mechanics to Real-World Impact: David Oliveira on Curiosity and Engineering Excellence

In Episode 3, Matt sits down with Dr David Oliveira, a respected geotechnical and rock mechanics specialist known for translating complex theory into practical engineering outcomes.With more than 25 years in academia and major project delivery, David has helped teams understand ground behaviour, improve modelling, validate assumptions and challenge the thinking behind “we’ve always done it this way.” This episode is packed with lessons for geotechs, tunnellers, designers and modellers who want to think deeper, work smarter and deliver engineering they are proud of.Additional ResourcesVisit our website: www.fullsendengineering.comEmail Matt: [email protected] with David on LinkedInIf you enjoyed this episode please like, comment and subscribe.
